This server has moderate definition quality with inconsistent tool documentation. Tool names follow verb_noun conventions well (getTokenInfo, getPoolInfo, executeSwap), and descriptions are present for all 11 tools. However, critical gaps exist: (1) Parameter descriptions are minimal or generic, most lack actionable constraints, ranges, or format guidance; (2) No output schemas are documented anywhere in the code, forcing LLMs to infer response structures; (3) No error handling guidance beyond basic HTTP responses; (4) Parameter dependency documentation is missing (e.g., how 'stable' param affects which pools are queried, or what happens if tokenA/tokenB don't exist); (5) Security parameters like WALLET_PRIVATE_KEY are passed via environment but no clear documentation of permission scopes or audit trails. The server handles 9 read-only tools and 2 write tools (executeSwap, addLiquidity), but write tool descriptions lack confirmation/dry-run patterns. Per-tool inspection reveals that while naming is solid, descriptions average ~70 chars (below the 194-char baseline for A+ tools), and no parameter has format constraints like min/max for amounts, enum validation for stable flag, or regex patterns for addresses.

• Document output schema for every tool as a JSON object with typed fields. Example for getTokenInfo: {name: string, symbol: string, decimals: number, totalSupply: string, address: string}
• Add min/max constraints to numeric parameters: amountIn (minimum 0, precision 18 decimals), limit (1-1000), amountB (minimum 0)
• Replace free-form 'stable' boolean descriptions with: 'Whether to use stable swap pools (true) or volatile pools (false). If no stable pool exists for this pair, the call will fail with pool_not_found error'
• Add address format validation to descriptions: 'Token address must be a valid Ethereum address (0x-prefixed, 40 hex chars). Use getTokenInfo to resolve symbol/name to address if unknown'
• Consolidate getQuote, getQuoteSimple, getQuoteRest into a single getQuote tool with optional route_type enum (simple|complex|rest) to reduce LLM confusion
• For write tools (executeSwap, addLiquidity), add dry_run: boolean parameter (default false) to enable confirmation-before-execute pattern. Dry run returns estimated outcome without broadcasting transaction
• Document error responses with recovery guidance: 'pool_not_found' → suggest searching getAllPools with tokenA/tokenB, 'insufficient_liquidity' → check current pool state with getPoolInfo, 'slippage_exceeded' → retry with higher minAmountOut
• Add idempotence declarations: 'executeSwap is idempotent if called with the same tokenIn, tokenOut, amountIn, minAmountOut within a 1-minute window. Same nonce ensures no duplicate transactions'
